RAILROAD-TIE Application filed September 10, 1906.

To all whom it may concern:

Be it known that I, EDWARD D. BENNETT, a citizen of the United States, residing at Pulaski, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Railroad-Tie Construction, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an improved railroad tie construction, and I declare that the following is a full, clear, concise and exact ,descri tion thereof sufficient to enable one skille in the art to make-and use the same, reference being had to the accompanying drawings in which like letters and numerals refer to like parts throughout.

Among the objects of the invention are to provide a rigid transverse support for the rails; to provide means of some resiliency for supporting the rails and which can be readily replaced, and a structure which will reduce to a minimum the tendency of a railbed construction to creep or weave in any direction and also prevent it from settling.

The construction comprises such a support which is to be embedded in the road-bed or set into the pavement of a street, the rails being immec iately supported by blocks which, projecting to or above the surface are accessible for repairs without disturbing the tie portion, and can be readily re laced since the cups which receive the rail-b ocks are of a uniform size. The blocks being comparatively small can be specially treated with preservatives at comparatively small cost and can be made in quantities for immediate use and of superior material without any great cost.

In the drawings Figure 1 is a side view of the tie showing the rail-supporting members thereon on which are mounted the rails. Fig. 2 is an end view of the construction, and Fig. 3 is a cross-section view through one of the rail-supporting blocks. Fig. 4 is a perspective view of a portion of the construction.

Referring to the figures more in detail, 1 represents a tie extending the width of the rail construction adapted to support rails thereon. The tie is formed with horizontal portions 2 and the downwardly extending vertical portion 3. These are of such extent that the horizontally extending portions cover a considerable surface of the ground or sub-structure on which the road is made,

giving the construction a maximum of suport. The downward extension 3 is perhaps little less than the superficial width of the tie and is embedded in the sub-structure or roadbed, its extended surface preventing the tie from side movement. This tie being properly placed in the road-bed and the material of the bed being thoroughly tamped about it and under it there is a minimum of opportunity for the movement of the tie either in settling or in sliding, because the bed material when properly tamped forms an abutment under the horizontal extensions and against the vertical extension and any movement tends to solidify or harden such abutment since the form of the tie utilizes any such movement in compressing the material of such abutment. In aved streets the tie itself is intended to be embedded in the pavement, thus giving perfect support and it being unnecessary to disturb it in repairing the rail supports.

A further advantage over some constructions is that the tie can be replaced, the substructure being disturbed to the minimum degree, because the horizontally extended parts are at the surface, and the road-bed can be easily tamped under such part. In other constructions I am aware rails have been made where there was a horizontal member, but this has been placed below the surface of the ground, rendering it more dif ficult to tamp under that surface and necessarily requiring that the substructure which is above the horizontal portion be more or less loosened by traflic over the rails. It is obvious also that such a tie could not be replaced without disturbing the sub-structure, whereas in my form of tie all traffic movement of the tie tends to press those parts of the sub-structure which support and hold the tie, while the arrangement is the simplest to permit thorough tamping and the tie can be lifted out of place and a new one substituted without disturbing the sub-structure.

Below the and at each side of the vertical are formed side walls 4, end wa is shown by 8 and which I show as bolted I forming supporting faces for the tie below through the bottom by bolts 9 and which the surface of the road-bed, each said box has at its exposed portion the cross-bolts 10.

At the same time the rail-supports or blocks can be I of such material and size as to allow all necessary yield in the bed structure.
